You end up back at 312.8 and you have to ask yourself IS "adequate space for this purpose is provided.".
I would bet a couple of 12 or 14 guage wires are not going to put this cabinet over 40% of the available wiring space. (or 75% of the cross section where the wires run)

Panel or Disconnect either can be 'run through' as long as there is enough space.

It would be darn near imposable to overfill a panel with branch circuit wiring.

Boy in the 60's they sure knew how to do it. I go to a lot of jobs with old GE load centers so packed up with wire the cover almost springs off when the screws are loosened. Of course the # of wires is still comparable to modern stuff, it's just the boxes were so little, and the long spare length's left on the wires before terminating at the breakers makes for a big crowd.
